Used vs refurbished vs new data center GPUs

"Refurbished" is not a single fact. On a data center GPU it can mean a card that an OEM repaired, a card a reseller wiped and retested, or a card someone cleaned and repackaged. The grade on a BreezeWish listing is the seller's choice of a defined value. BreezeWish does not inspect the card. Pair the grade with the checks before you buy.

The grades on the listing

The hardware schema used for these listings defines condition as one of: new and sealed, new and open box, refurbished, used grade A, used grade B, or for parts [S1]. Pick the row that matches the words in the listing. Do not upgrade it in your head because the photos look clean.

New and sealed means the seller says the factory seal is intact. Ask what "factory" is. A seal from a distributor is not the same sentence as a seal from NVIDIA's pack line, and the seller should say which.

New and open box means the seller says the unit was not put into service. Ask why it was opened, and ask for the pack date if they have it.

Refurbished means the seller is using that word. Ask who did the work, what was replaced, and what test they ran afterward. A seller-provided nvidia-smi or DCGM report is the evidence. A paragraph that says "fully refurbished" without a report is advertising.

Used grade A and used grade B are the seller's ranking of hardware that has been in service. The schema asks for hours in service on those grades and on refurbished units [S1]. Read the hours. Ask how they were measured. A GPU that sat installed for three years may show few high-load hours and still have calendar age.

For parts means you are buying something the seller does not claim will run as a GPU in a server. Price it that way. Do not plan a training job on it.

Warranty is a separate field

Condition is not warranty. The listing can say the warranty type is none, a seller warranty, or remaining OEM warranty, with months and whether it transfers [S1]. A refurbished card with "none" is a different offer from a refurbished card with twelve months from the seller. Ask who you call if the GPU fails in month two, and whether that person is the seller or an OEM you may not be entitled to call.

NVIDIA's product pages describe the new GPU [S2]. They do not describe the warranty on a used serial that has already been sold once. The remaining OEM warranty, if any, is the seller's document to show.

What to compare across grades

Compare the same form factor and the same memory size. An H100 SXM and an H100 PCIe are not two conditions of one card [S2]. A 40 GB A100 and an 80 GB A100 are not two conditions of one card. Once the product matches, compare condition, hours, warranty, and whether the baseboard is included.

A new sealed card can still be the wrong form factor for your chassis. A used grade A card in a complete HGX board can be the right purchase if the seller's report is clear and the title is clean. The grade does not answer those questions.

Hours and what they do not prove

Hours in service are whatever the seller entered. They are not a BreezeWish reading. Ask whether the number came from the BMC, from a cluster scheduler, or from an estimate. If the seller says "estimate," keep that word. An estimate is not a counter reading.

ECC errors, remapped rows, and retired pages, when the seller's report includes them, tell you more about a used GPU than the grade letter does. Ask for them on anything that is not new and sealed.

How to read a listing without inventing a grade

The public listing shows the condition the seller selected and the warranty fields they filled in. It does not show a score from BreezeWish. If the words and the photos disagree, ask the seller in writing and keep the answer with the serial list. If you cannot get an answer, do not invent a kinder grade in the purchase order.
