Two E5620 cpu - 400 watt PWS - will this be reliable?

[oppodoppo]

I am building a supermicro X8DTI-O with 2 x E5620's into a spare supermicro 2U case
with the OEM 400W PWS. Added twelve sticks of DDR3 1333 RAM, 2 Caviar 500GB drives,
and the 4 80mm system fans behind the HD backplane (power off the mobo).
Passive CPU heatsinks.

Using two molex on separate leads that are y'ed into a 2nd 8-pin EPS adapter. The
PWS only came with one 8-pin EPS connector. (Hint that this is a 1 Xeon PWS).

Seems like I am at the "red-line" for power delivery on this config from this PWS.
I don't many options from SuperMicro for a PWS replacement for this low cost
"SuperServer" (one CPU) case.

Am I OK, or do I need to re-think this?

Hello oppodoppo;

When I plugged your system into the PSU Calculator over @ http://extreme.outervision.com/PSUEngine it suggested a Minimum PSU Wattage @ 295 W and a Recommended @ 345 W.

You didn't list the PSU make, model or age so it's hard to judge it's quality.
But I think you're in a safe range with a 400W PSU.
