600 watt power supply enough?

[devilhanzou]

I currently did some upgrades to my computer and the specs are as followed

G. Skill 4 gigs of DDR3 1600 mhz
Phenom II quad-core X4 945 3.0 Ghz
Radeon 4850 X2
Mobo is a Asus M4a78T-E
250 gig 7600 rpm Hard drive
600 watt power supply

Every now and then when I first turn it on in the morning I get a Hyper transport synch error, I hit F1 to continue and never see it again until maybe the next morning, like a cold car or somthin. I goggled that a few times and came up with its an overclocking error, but I do no overclocking "wierd" I was thinking maybe I am pushing the limits of my power supply and might need to go up. If so what do u guys think I would like to upgrade to two 5800 series sometimes in the future but not going to just for DX11 I will wait till I can get somthing that will be a peformance upgrade cause right now I can play anything maxed out and it runs great. Also I am putting in 2-4 more gigs of memory soon, and will that be to much for my power supply? Thanks in advanced people on Toms have always been great help to me...

Hi.

A 600W should be enough IF this of a good brand like Antec, PC power and cooling, Silverstone, OCZ, Thermaltake or Corsair.

Here are the official power requirements for the ATI Radeon HD 5850 and HD 5870 video cards.


ATI Radeon™ HD5850 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

500 Watt or greater power supply with two 75 watt, 6-pin, PCI Express® power connectors.

600 Watt or greater power supply with four 75 watt, 6-pin, PCI Express® power connectors for ATI CrossFireX™ technology in dual mode.


ATI Radeon™ HD5870 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.

500 Watt or greater power supply with two, 75 watt, 6-pin, PCI Express® power connectors.

600 Watt or greater power supply with four, 75 watt, 6-pin, PCI Express® connectors for ATI CrossFireX™ technology in dual mode.

The power supply recommendations are for an entire pc system.


Corsair and Seasonic are two of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts series which is a major improvement over Antec’s older psu’s like the Basiq models.

K thanks saint and johnny for the info. I never new they meant an entire system I thought they were saying at least that much, Its good to know that. So really if I wanted to go from a 4850 X2 to two 5870 or 5850, I would be okay since I have a 600 watt PSU currently and its a Coolmaster so maybe not the best PSU in the world, does it get points for having a green light? JK... But I guess it would be safe to go a little above the recommened so maybe I dont need an 800 watt and could settle for a good 700 watt. Cause from what I have read it is better to have a good 700 watt over a cheap 800 watt

Coolermaster makes excellent cases. I can't say the same for their power supplies. Since you have not yet purchased new ATI 5000 series video cards my best advice would be to save a little more for a high quality power supply.

 

[saint19]

Yeah, you can have a cheap 1000W with only 55% or 60% efficiency or get a very good PSU like this

600 W IS Enough but make sure its a great brand PSU like Antec

 

[devilhanzou]

K peoples thanks for all the advice.
