Hello

I want to upgrade my current PC soon, ( early 2011) it current has a 600watts power supply

Just want to confirm if my current power supply will be able to handle something like this:

Intel Core i7-980X CPU

NVIDIA ENGTX480-2DI-1536-MD5 1.5G GFX Card

Gigabyte 890FXA-UD7 M/board

also would standerd case cooling be ok for this? Or should I buy a new case with a big fat fan on it

Hi.

Please supply the brand and model of the PSU as we need to know the watts and amps on the rails.

OK it is a Antec Brand

TruePower Trio

Model: TP3-650

It was actually a 650watt PSU

and I made a mistake on the M/board Im actually looking at this one:

Gigabyte GA-X58A-UD3R

Also would anyone be able to tell me what sort of cooling I would need to keep it running at a healthy temp? Ive read that the GTX480 card gets pretty hot

See my canned text on sizing and selecting a PSU:

Use the eXtreme PSU Calculator Lite to determine your minimum power supply unit (PSU) requirements. Plug in all the hardware you think you might have in 2 or 3 years (extra drives, bigger or 2nd video card, more RAM, etc.). Be sure to read and heed the notes at the bottom of the page. I recommend setting Capacitor Aging to 30%, and if you participate in distributive computing projects (e.g. BOINC or Folding@Home) or extreme 3D animated gaming, I recommend setting both TDP and system load to 100%. These steps ensure the supply has adequate head room for stress free (and perhaps quieter) operation, and future hardware demands. Research your video card and pay particular attention to the power supply requirements for your card listed on your video card maker's website. If not listed, check a comparable card (same graphics engine and RAM) from a different maker. The key specifications, in order of importance are:

  • Current (amperage or amps) on the +12V rail,
  • Efficiency,
  • Total wattage.
Don’t try to save a few dollars by getting a cheap supply! Digital electronics, including CPUs, RAM, and today's advanced graphics cards, need clean, stable power. A good, well chosen supply will provide years of service and upgrade wiggle room. Look for power supply brands listed under the "Good" column of PC Mechanic's PSU Reference List. Another excellent read is Tom’s Hardware, Who’s Who In Power supplies: Brands, Labels, And OEMs. Note that some case retailers “toss in” a generic or inadequate PSU just to make the case sale. Be prepared to “toss out” that supply for a good one with sufficient power.

Most PSUs have an efficiency rating of around 70%. This means for every 100 watts of power a PSU draws from the wall, only 70 watts is delivered to the motherboard, with the rest wasted in the form of heat. The best supplies are 85 to 90% efficient, and as expected, cost more. I strongly recommend you pick a quality supply with an efficiency rating equal to or greater than 80%. Look for 80 Plus - EnergyStar Compliant labels.

Too big of a PSU hurts nothing but your budget. Your computer will draw from the PSU only what it needs, not what the PSU is capable of delivering. If a computer needs 300 watts it will draw 300 watts regardless if the PSU is a 350W, 650W, or 1000W PSU. In turn, the PSU, regardless its size will draw from the wall only what it needs to support the computer. In this example, it will draw 300 watts, plus another 45 – 90 watts, depending on the PSU’s inefficiency.

As noted, the eXtreme Calculator determines the minimum requirements. If the calculator (with the changes I suggested) recommends a 400 watt minimum, a quality 400W supply will serve you just fine. But a quality 550W – 600W supply will have, among other things, larger heat sinks to dissipate potentially more heat. It might have a larger fan too. The 400W supply will run most of the time closer to capacity, while the larger supply will be loafing along, rarely breaking a sweat. To help the smaller heat sinks get rid of the wasted 80 watts (20% of 400) of heat, the fan in the 400W supply may need to run full speed, while the fan in the larger supply, with bigger sinks just loafs along too – but in near silence.

Don't forget to budget for a good UPS with AVR (automatic voltage regulation). Surge and spike protectors are inadequate.

thanks for your reply

The calculator actually worked out 1136 watts with:

Intel Core i7-950

NVIDIA ENGTX480 x 2 SLI

Gigabyte GA-X58A-UD3

6 sticks of RAM (assuming im going to have 1 gb sticks x 6 = 6GB RAM)

1 dvd/cw/rw Combo Drive

1 regular SATA drive

1 7200rpm IDE Drive


If I get a good quality 1000watts PSU do you think it will be ok?

thanks again

Hi.

I'll leave the PSU questions for our specialist Digerati to answer.

Mother board is a good choice but make sure when ordering to get the rev 2 as the earlier board had a few problems. Here is a link to an almost identical X58 board which has links to the UD3R as well. > http://www.bit-tech....x58d-e-review/1

What case do you have? You proposed build will generate a lot of heat and will need a lot of cooling.

I just have a standerd desktop case with my current PC

Looking to either get

CoolerMaster HAF 932 ( this one has liquid cooling correct?)

Or

CoolerMaster HAF 922 (no liquid cooling?)

Never had a liquid cooling case before not sure how it works

Which would you recommened?

Well, I get 1046 watts (with 3 120mm fans, high-end board, 100% CPU and TDP and 30% capacitor aging) recommended. With those settings, you have enough wiggle room with a 1000W supply - assuming a quality supply.

I'm not into liquid cooling. It certainly works - if implemented properly. But the problem is, once the novelty wears off, it becomes more of a chore to keep it maintained properly. And the issue there is that the older the system gets, the greater the need for regular maintenance to ensure there are no leaks.

Also note that CPU makers warranty their retail boxed versions of CPUs that come with heat sink fans for 3 years, but ONLY if used with the supplied HSF. Any damage from heat if used with any alternative cooling is covered by the warranty.

ok stuff the liquid cooling then lol

thanks for your advice

Getting really confused now with what card to pick

I definently know I want to sli or crossfire 2 good cards

but not sure which one to go

People have recommended the HD6870 CF compared to what I first wanted which was the GTX480 SLI, due to performance vs Cost and Heat, they said its cheaper and cooler, and runs just as good

but some people have also said GTX480 is better in performance

ARGGGHH this is fustrating me now lol, I dont know which one to get

Well, I am not a gamer so I don't need the most powerful card out there, and I especially don't need two cards. I do run a dual-monitor setup so I just need a good card with two digital outs. I suggest you check out Tom's Hardware Best Graphics Card for the Money, November 2010.

Hi.

My choice would be 2xHD6870 CF mode. Less power consumption, heat, better value than 1 GTX480. If you wanted 2 GTX480, they would be $1000 plus, Australian.

This is the best comparison table I could find, note that the table is for single cards. > http://www.digitalve...33&p2=8225&ph=1

Tell us where you are located so we can link you to the right sites for pricing?

Have you a max for your budget?

Im from melbourne australia

Ive saved so far about $2400

So I would prefer to get something good

Got a few quotes and the cheapest one is $2069

That is also with 2 x Gigabyte GTX480 SLI @ $430 each

Yeh I understand HD6870 might be more value for money, but if the 480s will provide more power then I might lean towards that because it fits within my budget

Might have cash left over for a bigger monitor or something

Just checked out that comparison on the graphs it shows the 480 a bit better

but on the specs the HD6870 has more mhz on its GPU Frequency and Memory, would of thought the HD6870 would be faster because of that

How *fast* a card is, does not only depend on the core frequency or memory. Other factors that effect it's performance are, pixel and texture fill rate, bus width, memory speed and more. Real world usage is the only sure way of knowing how fast a card is.

I use this site for finding prices, > http://www.staticice...u/advanced.html

I think most retailers would give a discount if you were buying 2 x GTX 480s.

Do you need more help with the PSU?
