I bought a supermicro chassis a few years ago with a 650W PSU for a personal lab I built. Everything has been just fine so far, but now that I'm looking into some GPU based work, I'm finding that I might be under powered.
I contacted supermicro's sales team to see if there's a compatible PSU that can give me at least 700W, hopefully 800W, unfortunately they informed me that 650W is the max for the case I have (CSE-833T-650B if you're wondering).
4x 7k RPM HDDs 2X E5620 Xeons 6 DIMMs ECC RAM Radeon HD 5990 with 1 EPS12v and 6pin PCIE power
The other problem I see is my PSU only has one EPS12v connector and a P4 connector. I currently have a P4 to EPS12v adapter to connect both EPS12v connectors on the motherboard. Would it be too much to fill both motherboard EPS12v with a Y adapter from the PSU's EPS12v plug, and then fill the Radeon's power with a P4 to PCIE 6+2 pin Y adapter (meaning convert 4 pin to 6 pin, and then split to a 6 pin and an 8pin).
My questions are these:
- Is monitoring the 12v rails levels is good enough to check for overload?
- Is my spaghetti mess of adapters and weak PSU a potential $8,000 nightmare?
- Is anyone aware of a supermicro chassis compatible brand of PSU for my case?
- Is there a way I can actually drop in a redundant system into my case that someone has experience with?
- Any suggestions beyond what I've considered are welcome!
