Why data center builders buy from us
A data center electrical parts supplier for the schedule you actually have: energization dates don't move because one breaker frame or bus plug is stuck on a factory lead time.
Speed
In stock means on our shelf in Princeton, TX: order by 3 PM CT on a business day and it ships today. OEM lead times on switchgear, breakers and cooling parts can run months.
Price
Surplus and sourced parts priced to win the line, and if you have a lower written quote, we'll beat it or take you to dinner.
One supplier for the whole list
Power, cooling, cabling and compute on one quote: what we stock ships now, the rest we source. Send an ISO list, RFQ or BOM as a spreadsheet or PDF.

Build-outs, expansions and critical spares
Data halls and AI clusters run on redundancy, and redundancy runs on parts. When a breaker, drive or power supply fails, the site keeps running on its backup path with less margin until the part is replaced; build-outs have the opposite problem, waiting on equipment to energize and commission. Our guide to data center electrical and controls spare parts shows how to rank a critical-spares list, then send it for one quote. And when a project ends with surplus breakers, busway or network gear, we buy that too.
Line down after hours or on a weekend? Call 469-316-8517 and we'll tell you the cost of sending someone in to ship your part, subject to availability, no fixed price.
Safety first: installing parts in a live facility is work for qualified personnel under your site's method of procedure, lockout/tagout and arc-flash rules.

Frequently asked questions
Do you supply data center construction projects as well as maintenance?
Yes. Electrical and fit-out contractors, MEP firms and integrators send us the lines holding up a build-out; facilities teams at colocation and hyperscale sites send spares lists. In-stock parts ship fast, and the rest we source and quote with the condition and lead time of every line.
How fast do you quote?
A single part: within 1 hour during business hours (Mon to Fri 9 to 4:30 CT). A whole ISO list, RFQ or bill of materials: a written quote in under 24 hours on business days.
How does the dinner guarantee work?
Send us your lowest written quote and we'll beat it. The terms: a written quote from another seller; same part number, condition and quantity; in stock, dated within the last 7 days; if we can't beat it: dinner in the DFW area, or a $100 dinner gift card anywhere else; one per customer per month.
Can you get servers, GPUs and networking gear?
Yes. What isn't on our shelves (servers, GPUs, switches, optics and more) we quote through our sourcing network. Send part numbers and quantities; every quote line states the condition and lead time.
Are the parts new?
We sell new, new surplus, used and refurbished parts, and the condition of every listing and quote line is stated. Parts we stock are photographed on our shelf, so you see the actual unit. We are an independent seller: our own return policy covers every order, not the manufacturer's warranty.
Can we pay by purchase order, and do you ship outside Texas?
Yes. Send your PO against our quote and we invoice it; payment is by card before we ship. We ship nationwide, and standard international shipping is a flat $110.00 per order.
