MCW50-T and system PSU

[Malves]

I'm going back to water. I'm planning to put a MCW50-T on my Radeon. Since it's a 80W pelt, can I use my system's PSU? I have an Antec TruePower 430, modded.

Also, on my list I have a Camry 88 heatercore that will take 2 120mm fans (just like the famous BA from Cascade). Is it big enough to take the heat from the water?

Probably. If the voltages have dropped substantially, after plugging in the TEC, unplug it and find a dedicated PSU, or a beefier system PSU.

Yeah, that heatercore should do quite well.

Swiftech put a 4 pin molex on it for you to use on your system PSU, it will be fine.

I think it might take too much power depending on the rest of your system......

I'd think about a 350watt fortronn for it personally.

Besides what's on my sig: 2 HD's, 1 DVD-ROM, Floppy, 4 case fans. Plus I'll have the Swift MCP600 that goes on the 12v line.

I also have another question. I used to have a R95P, and anything above 325 on GPU would give artifacts. Then I got a MCW50, hook it up to my VC and I was still getting artifacts, then I did the mod and it was fine.
But, now I have a R97P modded that goes up to about 450, anything above that and I have artifacts. I'm kinda afraid of spending the money and trouble with a TEC and do not get more speed out of my Radeon, because of the past experience with my old 95P.
I feel like if I just get a MCW50 or a DD4, will be enough just to keep my Radeon cool @ that speed. Any thoughts?

Well, a regular waterblock will keep it plenty cool, A TEC just gets it a bit colder.

If you don't want the hassle, a waterblock will still keep it cool.
