Windows 7: would i need to upgrade my PSU?

TVeblen is correct about Seasonic. But for some reason in most of the reviews I read, seasonic doesn't get as good reviews as Corsair. I don't know why and find it strange that they would build a better PSU for others. But, at any rate I have 2 Corsairs HX650 and HX750. Neither has caused one bit of problems. If I need another it will be an HX corsair model.

I looked at a couple of 5770s, and both "required" 450W PSUs.

On the other hand, the 5770 uses a single 6 pin PCI-E power connector, so it must consume less than 150W.

Maybe the "450 W" bit is calibrated to inferior PSUs. I'd expect a good 400W one to be more than adequate, especially if you're not using 200W+ to power a massively overclocked CPU.

I've been quite pleased with my PC Power & Cooling Silencer 750. (It's a single rail unit, 60A at +12V.) It has only two drawbacks: it's not modular, and it's painted ATI red.

bobkn. I have a 5770, it graws 70W. Manufacturers are notorious for overstating the required PSU. Maybe CYA?

  • PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
  • 450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)
  • Certified power supplies are recommended. Refer to AMD Certified Power Supplies for a list of Certified products
  • Minimum 1GB of system memory
  • Installation software requires CD-ROM drive
  • DVD playback requires DVD drive
  • Blu-ray™ playback requires Blu-ray drive
  • For an ATI CrossFireX™ system, a second ATI Radeon™ HD 5770 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required
check before u jump!! u need an extra pSU indeed! cause the PHENOM II X4 =95W and u got ur HDD and other things runs! the good thing for ATI is it consumes less power! and rarely requires a COOLER! happy Gaming!!

CYA? In a way.

Cheapest 450W PSU at Newegg with at least one PCI-E power connector:

Newegg.com - Diablotek PHD Series PHD450 450W ATX12V V2.2 Power Supply

Diablotek PHD450, 24A at +12V.

One that costs twice as much as much:

Newegg.com - SILVERSTONE ST45SF 450W SFX12V 80 PLUS BRONZE Certified Active PFC Power Supply

SILVERSTONE ST45SF, up to 36A at +12V.

A fairly low-end Antec 380W piece:

Newegg.com - Antec EarthWatts Green EA-380D Green 380W Continuous power ATX12V v2.3 / EPS12V 80 PLUS BRONZE Certified Active PFC Power Supply

Antec Earthwatts EA-380D, 17A/15A on its two +12V rails.

A cheap "600W" PSU:

Newegg.com - Broadway Com Corp OKIA-BLACK-600 600W ATX 12V V2.2 SLI Ready CrossFire Ready Active PFC Power Supply

Broadway Com Corp OKIA-BLACK-600, 13A/16A on its two +12V rails.

If the numbers can be believed, the Antec 380W supply should be more useful than the Broadway "600W" unit.

The reviews on the Antec are considerably better also.

I second all the Corsair and Antec recommendations. I love my Corsair HX750.

I have a HX 650 abd HX750 and love them both. Unless I am mistaken,both the Corsair and Antec are made by Seasonic. And BTW, once you build with modular, you will never look at anything else.

thanks for the recommendations guys. i was told when i bought my Corsair that the CX400 was a quality PSU and i cannot agree more, but i just feel 400 for running as much as i have pretty strenuous. i built my intel build with a kingwin modular, great power supply, nice blue fan and more than enough cables.
